This week I've made some link submissions to some directories, and I was checking to see if Google updated the cache for my website, and when I've entered site:my website I've got 0 results from Google, 0 pages indexed. Why this happend ? And what can I do to get back in Google. Any experiences with this kind of problem ?
I dont know what happened (not enough info) but I can assure you it had nothing to do with your submissions to directories. If that were the case I could submit all my competitors websites to directories and then I would own 100% of the SERPs for my keywords.
If you have any competitor or recently received any request to remove certain pages from your website, it's likely that you got DMCAed. When Google received a DMCA regarding copyright infringement, they will remove your site from their indexes. It happened to me. Google your website's name. Scroll to the bottom of the results. Look for a message about DMCA. Check: www.google.com/dmca.html
Same happed with my sites a lot of times, but after some hours / days sites come back. So wait for few days, and if you not did some work against google terms your sites will come back.
Yes, the sunglasses one. I know this, but I want something that might be helpful. I don't see any DMCA message at the end of results, you can take a look to. No duplicate, no redirect. I hope you're right, I'll wait some time, and keep you informed. The url is the sunglasses one from my signature, and the website has more than 1 year.
